The documentation does mention that other fields inside the

traits

section can be used for account recovery, but it does not specify what these other fields could be. The

traits

section is part of the identity schema and can be customized to include various fields based on your application's requirements. However, the examples provided in the documentation primarily use the

email

field for account recovery. For instance, the identity schema example provided for account recovery uses the

email

field:

json {     "$id": "<https://schemas.ory.sh/presets/kratos/quickstart/email-password/identity.schema.json>",     "$schema": "<http://json-schema.org/draft-07/schema#>",     "title": "Person",     "type": "object",     "properties": {     "traits": {     "type": "object",     "properties": {     "email": {     "type": "string",     "format": "email",     "<http://ory.sh/kratos|ory.sh/kratos>": {     "credentials": {     "password": {     "identifier": true     }     },     "recovery": {     "via": "email"     }     }     }     }     "additionalProperties": false     }     }   }

In this schema, the

email

field is marked for recovery with

"recovery": { "via": "email" }

. For more details on how to customize the identity schema and use different fields for account recovery, you may want to refer to the [Ory Kratos documentation](https://www.ory.sh/docs/kratos/self-service/flows/account-recovery-password-reset#account-recovery-address).
